LINE INDCATOR F01?.- TYEEW'RITING MACHINES.

Application filed July 14, 1924. Serial No. 725,9591f.

To N 107101)@ Ah5 may concern Be it known that I, Vieron Konmar:-S'raminn, a citizen of the Republic ot' Switzerland, residing at Zurich,Switzerland, have invented certain new andA useful Improvements in LineIndicators ior Typewritingil lslachines, ot which the following is aspeciiicati'on, reference being had therein to 'the accompanyinp,`drawing.

This invention relates to improvements in line-indicators tortypewriting` machines provided with copy-holders. The line indicatoraccording' to the present invention comprises guid means to be tixedclose toV thel typewritinp; machine in a substantially horizantalrposition and approximately in the same. elevation as that 'in which thehandset' the operator are.` an endless pulling' member 2rui-ded in saidmeans, turther other guide means to` be iixed in. an upright directionon the copy-holder in which means the endless pulling` member is also`guided, a slide adapted to be guided in the first men tioned guidemeans and connected to one part of the endless pulling, member, and asecond slide carrying the lineindicator and adapted to be guided in thesecond mentioned guide means and connected to the other part of theendless pulling; member.

A constructional example of the line indicator according; to the presentinvention and attached to a typewriting machine having a copy holderprovided with a supporting` plate on which the typewriting machinerests, is illustrated on the accompanying drawings, in which:

Fig. 1 is a front elevation of the device,

Fig. 2 is a. side elevation,

Fig. 3 shows on an enlarged scale part ot the device and of thecopy-holder, y

Fig. et is a section along line lV-IV in Fin). 3, and

Fig'. 5 shows part oit a modified embodimentot the line-indicator.

Referring now to the drawing, 1 denotes the supporting plate, madey forinst-ance ot wood and covered with a fabric or telt 2. To the plate 1the. traine 3 'is liXed which is provided in its upper part with aswing'able stirrup e, the lat-ter is clamped frictiontig'ht in the:trame 3 so that it remains in every adjusted position. The copy-holder5 is turnable and friction-tight on the stirrup and retained in everyposition.

6 denotes a rail fixed at one side of the plate 1. To the rail 6 a guiderail 8 is removably attached by means of resilient clampingV members T.The guide rail 8 extends trom the 'front to the rear and is arrangedsubstantially horizontally. A slide 9 is displaceably mounted on theguide-rail 8, the lower ends 10 oi the slide being bent to embrace theguide rail 8 whereby the slide is Lguided on the rail 8. A part of theendless pulling member 11 is fixed to the slide 9 and the pulling member11 passes, over a roller 12 on the rail 8 and i-s guided from the rearendY ot the rail 8 onwards by means ot two separate flexible tubes 14and 13.

At one side of the copy-holder 5 a further guide rail 15 is removablyattached by means oit' resilient clamips 16,. the rail 15 eX- tending inthe upward direction. slide 17 is movable along the guide-rail 15 and isof a substantially similar design as the slide 9', i. e.,1 also providedwith bent lower parts which embrace the rail 15. The pulling member 11on leaving the other ends ofthe tubes 13 and lfl passes below the guiderail 15 andV around a roller 18 fixed tothe lower end ot rail 15; theslide 17 is also iXed to the pulling` member 11 which is endless. To theupper slide 17 at the c0py-holder a lineindicatoror rule 19 is rotatablymounted by means oit a crank 20. By turning the milled knob 21 the rule19 may be turned from the position indicated in Figi'. 1 in full linesinto that indicated in ehaindotted lines.

When the slide 9, which is conveniently arranged at the same elevationas that ot the hands oi the operator, is displaced in the direction ofthe arrow a? 2) a movement of the slide 17 and thereby ot thelinewindicator 19 is caused in the direction of the arrow .1/ (Fig. 2)and the extent of the movements of both slides is equal to one another;the movements of the slides are exactly similar and are no step by stepmoven'ients. By moving the lower slide 9 the upper slide can be moved upand down by any desired amount so that the tire.- some directdisplacement of the upper slide 1.7 to which end the hand has to beraised, `s no longer necessary. ln order to permit adjustments of theline-'indicator by any desired amount and in any direction the use ofsprocketwheels, racks and the like has been avoided and a line-indicatoris thus provided which is very simple and reliable and which can easilybe adjusted.

VVithl the constructional `example illustrated in Fig. 5 a pivot joint22 is inserted in the wire bent like a crank 20 so that the lineindicator' 19 may be inclined to the horizontal.

Instead of carrying one of the guide rails at the side of thesupportingI plate it may be arranged at the writing table, if nosupporting plate is used or at the typewritinp, machine as will bereadily understood.

I claim:

1; A line-indicator for typewriting machines provided with copy-holders,comprising in combination guide means adapted to be iixed close to thetypewriting machine in a substantially horizontal position andapproximately in the same elevation as that in which the hands of theoperator are, an endless pulling,` member, further guide means adaptedto be fixed in an Upright direction on the copy-holder, a slide adaptedto be guided in said first mentioned guido means and connected to theendless member, and a second slide carrying a line indicator and adaptedto be guided in the second mentioned guide means and connected to theendless pulling member.

l. A line-indicator for typewriting machines provided with copy-holders,comprisinp,` in combination guide means adapted to be iixed close to thetypewriting machine in a substantially horizontal position andapproximately in the same elevation as that in which the hands ot' theoperator are, an endless pulling member, further guide means adapted tobe lixed in an upright direction on the copy-holder, a slide adapted tobe guided in said iirst mentioned guide means and connected to theendless member, a second slide comprisinga lincindicator and adapted tobe guided in the second mentioned guide means and connected to theendless pulling member, and two tubular guides for the endless memberinterposed between said two guide means.

3. A line-indicator for typewriting machines provided with copy-holders,comprising in combination a guide rail adapted to be removably fixed bymeans ot' resilient clampingmeans close to the typewriting machine in asubstantially horizontal position and ap-- proximately in the sameelevation as that in which the hands of the operator are, an endlesspulling member, a further guide rail adapted to be removably .fixed inan upright direction to the copy-holder, a slide adapted to be guided insaid first mentioned guide means and connected to the endless member,and a second slide carrying a line-- indicator and adapted to be guidedin they second mentioned `guide means and connected to the endlesspulling member.

In testimony whereof I a'lix my signature.
